HEADLIGHT.

Application filed April 17, 1916, Serial No. 91,510..

To all whom it may concern:

Be it known that I, OVERTON WVINsToN, a citizen of the United States,residing at Minneapolis, in the county of Hennepm and State ofMinnesota, have invented certain new and useful Improvements inHeadlights; and I do herebydeclare'the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My present invention relates to headlights for automobiles or othervehicles and is in the nature of an improvement on or modification ofthe means for adjusting the light bulb-thereof, disclosed and claimed inmy earlier application S. N. 86,851, filed of date, March 27th, 1916,and entitled Headlight.

Generally stated, the invention consists of the novel construction andcombination of parts hereinafter described and defined in the claims. 7

In the accompanying drawings which illustrate the'invention, likecharacters indicate like parts throughout the severalviews. 1

Referring to the drawings:

Figure 1 is a vertical section taken centrally through a headlightembodying my invention; and Fig. 2 is a fragmentary view in frontelevation showing parts found in the vicinity of the line marked waa onFig. 1.

v The numeral 1 indicates the case of an ordinary headlight such as usedin automobiles, and the numerals 2 and 3 indicate, respectively, thereflector and the lens or glass plate of the headlight. The electricbulb 4 is of well known or any suitable type and is detachabl held in alamp socket, such, for examp e, as .that illustrated in my priorapplication above identified, and

which lamp socket is indicated, as an en tirety, by the numeral 5.

The lamp socket 5 is pivoted at 6 to a hollow supporting head that isprovided with a threaded shank! screwed into an annular anchoring plate8 that is rigidly secured to the back of the reflector 2 and surroundsan axial passage 2 in the latter. The passage 2 affords clearance forthe front end of the lamp socket.

For oscillating the lamp socket vertically,

intermediately Patented Sept."1'7, 1918. Renewed February 15, 1918.Serial No. 217,460.

I provide upper and lower electro-ma'gnets 9, both of which are rigidlysecured to and tory movements of the rear metallic sleeve portion of thelamp socket 5. r

. Small upper and lower lock levers 10 are intermediately pivoted to theflanges 7 and are provided at their inner ends with lock heads 11. Theouter ends of said levers 10 are yieldingly pressed rearward by lightsprings 12, shown as anchored to the flanges 7. The outer ends of thelevers 10 serve as armatures that are adapted to be retracted by theouter pole pieces 9' of the respective electro-magnet's.

The operation of the lamp socket, electromagnets and latches, is thesame as disclosed in my above identified prior application, andhence,"for the purposes of this case, it jis. only desirable to statethat when the upper electro-magnet is energized, it

will draw upward the rear endbf the lamp socket so as to move the lampdownward to a point where its filamentwill be at the axis ofthereflector, and in this position, the

socket will be locked by the lower latch lever. The release of the upperlatch lever is, of course, accomplished before the socket can move. Inthe raised position of the light bulbrshown by full lines in Fig. 1, theupper latch lever holds the rear end of the lamp socket downward. Itwill, of course, be understood that when the lower electromagnet isenergized, the lower latch lever will be first released and then therear end* of the lamp socket will be drawn downward, asshown by fulllines in Fig. 1.

In the said prior application, no positive devices were shown either forholding the supporting head 7 against rotation, or for supporting thesame from the'lamp casing, as well as from the reflector. The presentinvention is directed to means for accomplishing these two results, andit is preferably accomplished as follows: The lamp casing is providedwith rigidly secured vertically spaced and vertically alined anchoringflanges 13 having approximately parallel edges that are annular anchorinthus positioned,

port and the I to support an electric arranged to engage ooves 14 in theouter faces of the outer po e pieces 9. Preferably, also, the slotengaging edge of one of the anchoring flanges 13 "s faced with a leafspring 15 which will take up slack and prevent rattling, if therehappens to be play between the two anchoring flanges and the engagingpole pieces of-the electro-magnets.

I Inassembling the arts of the device, the threaded shank of t esupporting head 7, would preferably be plate 8 on the back of thereflector, whi e the reflector, of course, is removed from the casing.Then the reflector will be placed in proper position, in respect to thecasing by a rearward movement with the grooves 14 of the pole pieces 9engaged with the parallel edges of the anchoring flanges 13, and theelectromagnetsthereby slid back to final position shown in Fig. 1. Whenthe said parts are the. so-called anchoring flanges 13 positively lockthe head 7 against rotation, and afford a solid supporting connectionbetween the electro-magnets and the casing. In this way, the lamp socketsupvibration and afford a base connection between the reflector andcasing.

What I claim isz v 1. In a headlight, the combination with a casing anda reflector therein,'of a socket support connected to the back of saidreflector by screw-threaded engagement, parts of 'said socket supportand casing having interlocking engagement, and a lamp socket mounted onsaid socket support in position light bulb within the said reflector.

2. In a headlight, the combination with a casing and a reflector, of-asocket support connected to said reflector by screw-threaded engagement,a lamp socket pivoted to said socket support and electro-magnetic meansfor oscillating the socket, and an interlocking connection between saidsocket support and casing holding said socket support against rotation.

3. In a headlight, the combination with a casing and a reflectorremovably mounted therein, of a socket support connected to saidreflector by screw-threaded engagement, a lamp socket pivoted to saidsocket support, an electro-magnet on said socket support, for operatingsaid lamp socket, an anchoring flange on the interior of said casing,and an interlocking sliding connection be- Ooples of this patent may beobtained! first screwed into the electro-magnets are held against acasing and a reflector removably mounted therein, of a socket supportconnected to said reflector by screw-threaded engagement, a lamp socketpivoted to said socket support, upper and lower electro-magnets foroperating said socket, and upper and lower anchoring flanges on theinterior of said casing, said electro-magnets at their outer extremitieshaving interlocking sliding engagement with said anchoring flanges, oneof said anchoring magnet engaging edge spring to take up play.

6. n a nheadlight, the combination With a casing and a reflectorremovably mounted therein, of a socket support connected to saidreflector ment, a lamp socket pivoted to said socket support, upper andlower electro-magnets faced with a leaf secured to said socket supportand opera portd by said reflector, and anchoring flanges on the interiorof said casing having sliding interlocking engagement with parts carriedby said socket-support.

In testimony whereof I affix my signature in presence of two witnesses.
